SPECIFICATION forming part of Letters Patent N o. 512,383, dated January 9, 1894. Application led July 6, 1893. Serial No. 479,750. (No model.)

To @ZZ whom- L' may concer/tr' 1Be it known that we, JOSEPH MANDEL and JAMES P. HENDERSON, citizens of the Unitedv States, residing at Logansporhin the,county of Cass and State of Indiana, have invented certain new and useful Improvements in Machines for Inserting and Olinchig Staples; and we do hereby declare the following to be afull, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates generally to machines for inserting and clinching staples, and particularly to a machine for inserting metallic staples or fasteners through one or more thicknesses of cloth, paper, felt, or like material, and for clinching the legs of the staples around reinforcing plates held in position on the under surfaces of the materials operated upon, and through holes in the. ends of which plates the legs of the staples pass, which will hereinafter be fully described, and particularlypointed out in the claims.

Our invention, while it may be used for other purposes, is especially designed to provide means for reinforcing the corners ofthe pockets of coats, trousers, and other wearing apparel, where they are subjected to strain, -in such a manner as to greatly cheapen the sewing upof such garments, while providing amore certain preventative from tearing than is provided by the present means used. In place of the present laborious stitching which has to be resorted to to prevent such tearing, .We propose to substitute a simple mechanical fastening, which can be inserted by a single operation of our machine around a suitable `reinforcing plate, which is held by the operation of our machine in position, on the under surface of the material tovbe acted upon, for the legs of the staple to pass through holes in its ends. Clinching means are provided for turning the protruding legs of the staple up under the pla-te and-,fr securely. clinching them-there. The fastening thus afforded is much more secure than that at present used, and is also much more dtirable.

Our invention is an improvement on the form of staple inserting and clinching machine shown and described in United States Letters Patent No.-3S9,66l, granted to us on September 1,8, 1888, and has for its object to reduce to a single movement, caused by the 'depression of a single foot lever, the number 55 of movements necessary to hold in position the staple, and the reinforcing plate, to insert the staple through the holes in the plate, to ciinch the legs of the staple around the plate, and to place a new staple and a new plate in operative position, instead of having to perform these operations separately, as was necessary in the use of the machine referred to.

Our invention consists, thereforez-First. In improvements in the staple holding and feeding device, whereby staples, held upon a suitable former, are one -by one automatically forced into position to be engaged bythe staple inserting mechanism, and inserted into the cloth, or other material operated on. XVe ,l provide means for interrupting the forward A feed of the staples while the staple inserting mechanism is operating, in order thata second staple may not crowd into position in the path of the same while it is forcing one stapleintc position. The mechanism for effecting this vend is operated by the descent of the staple inserting mechanism. Second. In improveu ments in the staple inserting mechanism, whereby the movement of the same is sim` plicd, and its operation made certain .and complete. The staple inserting plunger is so connected with the staple feeding device that it automatically cuts oli' and allows the feeding of the staples into posit-ion in the staple guide block in which the said plunger reciprocates. Third. In improvements in the plate holding and feeding device, whereby the successive placing of tho plates into operative position over the central aperture formed' in the machine bed is automaticaily accomplished by means operated by the action of the staple inserting mechanism. Fourth. In improvements of thc clinching mechanism, whereby the same may be actuated by a further movement of the same' mechanism which operates the staple inserting mechanism. In our machine the clinchy ing mechanism-is situated in the central aperture, formed in the machine bed. Fifth.

whereby the various portions of the staple in-P earting and clinchingmechanism are lsuccessi-'ely caused to perform their functions in due order, and without danger of confusion in operations, by mechanism operating bythe depression of a single foot lever.

Our invention is fullyrepresented in the drawings accompanying and forming a part of this application, in which the same reference numerals refer to the same or corresponding parts, and in which- Figure 1 is a perspective view of the top portion ofour machine, the operative mechanism, and the parts immediately brought into operation thereby being hid by the top of the table. Fig. 2 isa side view of the machine partially in section, showing the various parts in operative position, and ready to be actuated to insert a staple intdthe piece of cloth laid on the bedvplate of the machine. Fig. 3 isa similar view, the parts being shown in the position they-assume when the staple has been inserted, but before the clinching mechanism has begun to act. Fig. It is a similar view, the clinching mechanism being shown as just; having completed its operation, and before it has resumed its normal position. Figs. 5, 6, and 7 are detail views of the head of the staple feeding mechanism, and the staple plungerV operating vin connection therewith. Fig. 5 shows the parts in the position they assume before the staple inserting plunger has begun to act, the sliding gates which interrupt the delivery of the staples being shown open. Fig. 6 is a similar view, the parts however being shown in the position they assume when the staple inserting plunger has just. completed the operation of inserting a staple; lThe sliding gates before mentioned are here closed. In both of these igures the outer, removable por tion of the staple guide block is removed, in order to show the interior parts. Fig. 7 is a section of Figs. 2, 3, o'r 4, taken on the line w and looking in the direction of the arrw.4

It is a rear view of the staple guide block, and shows particularly the means adapted to normally hold the sliding gates open. Figs. 8, 9,

and 10 are views ofthe clinching mechanism,

the views respectively showing the staple inserted and ready'to be clinched; the legs of the staple turned in in readiness for thetnal clinching; an The metal plate which holds the blades performingthe clinc'ning operation imposition on the machine, and which also forms one side of the central aperture, is hereremoved, in order th during the entire operation may be readily ascertained. The hammer actuating the clinching mechanism is here shown in section. Fig. 11 is a view of the inner surface of the outer, removable portion of the staple guide Tfzock. Fig.12 is a view of one of the curved blades which perform the clinching operation. Fig. 13 is a view ofthe locking device eind the staple lfinally clinched.v

Before proceedingwith adescription of our machine, it is well to thoroughly understand. the formation ot' the staple, and the Vreinforc- 75 ing plate upon which the machine operates. These are described in United States Letters Patent'No. 389,660, granted to us September L8, 1888, and as there described the reinforcing plateconsists of a piece of metal, formed with 8o holes in its ends for the reception of the legs ofthe staple, and formed with a, central, 1on gitudinal slot for receiving the clinched legs of said staple. Itis intended that thelegs of the staple, when clnched,shall just meet in 8f; thecentral slot, without "overlapping, so that the under surface of the goods will be smooth. v It is thus necessary to use staples having different lengths when opera ng upon different l thicknesses of cloth, in orde. that the legs may 9o not overlap.

Proceeding now with thed-escription of our machine, and referring to the accompanying drawings, -1 represents the table upon which our machine is placed.

2 represents the main'orcent'ral casting, which vforms thebed of the machine. This Vcasting is shown in perspective in Fig. 1, but its shape is more clearly indicated in Figs. 2, 3, and 4. Broadening at its rear end, which is at the back of the tab`f^. so as .to secure a firm base Vby which it car .ecurely attached to the table, it rises ps- .dicularly at the front,central vportion of its rear end until the desired height'is attained, and then extends foi-ward horizontally, constituting the bed proper .of the machine.V At the front end of the casting tivo side arms branch out in the form of a T, and to these arms are attached the brackets 4, which t-hustirmly support the front end Aot' the casting at the desired'height. To this broadened front end, and at a distance alittle greater than the -width of the legs of a staple, is secured, by means hereinafter to be described, 'the plate 5,' which thus forms in effect an extension of the machine bed. Thefaperture thus formed between the 'bed 2 and the plate 5 is called-the centralaperture, as it is overthis aperture that/therevinforcing plate is held when ready to be operated upon; it is in this aperture that the legs of the staple pass, when they have been inserted through the cloth being operated upon; and it is in this aperture that the clinching mechanism is located. On the top of the machine bed is fastened the' bed plate 6, in the front end of which, and directly over thecentral aperture, is formed an opening?7 which is of just the size of a reinforcing plate, except on its front edge,where it is holloi'ved out for a purpose hereinafter .to be stated. This opening holds the reinforcing plate di rectly in position 'over the central aperture formed in the bedplate. To the machine bed ICO IIO

` block; the

.staple guide, and the hammer are pivoted the staple holding and feeding device, which has in connection therewith a staple guide block, normally held above the central aperture by its lconnection with the staple inserting mechanism, but whose pivotal movement is such that when the staple holder is depressed, the opening in the same 'registersjwith the central aperture directly over the place where the reinforcing plate is held; the staple inserting mechanism, with the staple inserting plunger` connected therewith, and also connected to the staple guide plate feedi ng mechanism, operated by a lug formed on the rocking arm which constitutes the operative means for reciprocating the staple inserting plunger in the which operates the clinching mechanism. The blades performing the clinching operation are also pivoted in the central aperture.

The operative mechanisms of our machine may be divided into the staple holding and feeding device; the staple inserting mechanf ism; the plate'jholdingand feeding device; the clinching mechanism; and the operative .mechanism by which all the separate mechanisms are actuated.

For convenience of description, and in orthe various parts. may be grasped indetail, and thus thoroughlycomprehended, the various portions ot the entire machine will be described separately in the order mentioned, allusion being made from time to time to the other parts in order te clearly keep in mind the timing of the various movements, which enables all of the different mechanisms to operate to accomplish a single end. Ai ter such `separate descriptions, the entire operation of the machine will be described, and the timing of the various parts clearly ascertained.

I. The Staple hold/ng and feeding mecha-nysim-Between two lugs S, projecting upward from the machine bed 2 at the extreme rear end of the horizontal portion of the same, is pivoted the staple holding and feeding device 10, which consists of a staple holder l1,- a tube 13, located immediately in the rear of and connected to the same, in which is located the feeding device, and a stapleguide block 30, which is placed at the front eind of the staple holder. The proportions of the parts are such that when the staple guide block is at the lower stage of its pivotal movenient, the staple guiding recess formed in the same registers with the central aperture, over which the reinforcing plateis held. The staple holder consists of the U-shaped trough 1l, which is of sufficient size to permit the in- -Go 'sertion therein ot' the staple carrier 12, upon which the staples are arranged, and also to permit the free forward passage of said staples, they a-rc pushed forward by the sta pie feeding device, which is located 1n the tube 13. of wood, paper, or other suitable material, so formed that the ,staples will fit snugly The staple carriers 12 `are pieces! l nently loeli the plunger 1n its withdrawn poover them, and of length sufficient to hold the desired charge of staples for the machine. le nsully charge the machine, when about to operate the same, with a gross of staples, and a gross' of plates, asit is convenient to put up the staples and plates in charges of tha-t number, but the charge can of course be varied by changingthe proportions of the machine. In the bottom of eachv carrier is formed a groove l2', into which the studs 14, which project centrally from the bottom of the trough 11, enter, and thus hold the carrier in position in the said trough, and prevent it from getting twisted or turned to one side. The ends of each carrier are inclined on its bottom surface, so that by pressing on one end, the other end will be raised out of the U-shaped trongh,and can be more easily grasped for removal from the staple holder. By thus making the carriers removable, the recharging of 4the machine, when the supply of staples becomes exhausted, is made easy. The carrier is held in position lengthwise in the staple holder by two U-shaped lugs, 15 and 15', which project from the bottom of the tronghfll. These lugs, as the staple carrier, are shaped to ttthe inner surface of the stat ple. The forward lug 15 is in effect merely au extension of the staple carrier. The said lug extends from the extreme edge of the sta'- ple bolder to a point a little behind the head 3l, which forms a portion of the staple guide block. The rear lug, 15", is only of suiicient length to make it firm and secure. In the tube 13, which is attached to the staple carrier immediately at its rear, is located thp spira-l spring 1G, which acts, through the inediationot the plunger 17, to constantly force the staples forward. The plunger consists of a strip of metal of the width of the U- shaped trough, which is formed at one end with a downwardly projecting lug or ear 18, which is inserted' behind the Ushaped lug 1.5', and against which the spring 16 directly bears, and at the other end with downwardly turned side flanges, which extend to the bottom ofthe trough 11. By so fpdrming'the head of the plunger, a constant and uniformpressnre against the staples is secured throughout the entire travel ot' the plunger, as its length is sufcient to enable it to feed the last staple from the staple holder. 0n the top of the plunger is the rib 20, tothe front end of which .is attached the trigger 2l, by means of which the plunger maybe drawn back. To the downwardly projecting lug 18 is attached the rod 22, which extends through the tube 13 suini ciently far to cause the lug 22', formed on its rear end, to pass through the opening 13 formed in the end of the tube 13, when the plunger is pushed backward as far as possible. The spring 222, attached to and pressing on the rear end of the rod 22, will then cause said lug 22 to engage with the side offthe4 aperture 13', and thus perma sitiou.. lt may be released by pressing up- IOO tog

- loaded carrier into the staple holder, the pivward, and out of engagement with the side of the opening 13, the said lug 222. The holderA in the back of the head 3l, a lug 25 limiting its lforward movement. Itis locked in position on the holder bythe pivoted fpawl 23, pivoted tothe topof the tube 13, which when properly turned engageswith therear end of said cover. When 'it is desired to insert a oted pawl 23 is turnedso as to permit'otthe removal of the cover, theplunger 17 is withdrawn until it is locked on its rear position, and the old former is taken out. carrier has been inserted, the cover is again placed in position, and then the plunger 17 is released. It is important that the cover be put on the holder before the plunger is re'- leased, as it acts to prevent the staples from risingont of position, and thus interrupting theforward feed of the staples. On the front end of the staple holder is formed the staple guide block 30, which is formed in two portions of the head 31,and the removable piece 38. The head 3.1Y is nearly square in form. On its upper surface are formed two projections for the reception of the p'ivotal boltsfor the levers 33. Its lower surface is somewhat Aftera newA open by the U-sh'aped spring 35, shown in Fig. 7. The lower portion of this spring is as shown, and the side arms of the same, proi jecting upward, engage'with lugs 33', which project from the back surfacesl of the levers 33 below the pivotal point of the same, and

- ward. The range of movement necessary to close the sliding gates is not great, and can be varied by proper adjustment of the relative '-engths of the arms ofthe levers 33.

staple inserting mechanism consists of a plunger, which reciprocates in the staple guide 30, andarocking arm for actuating the same, ,which is pivoted to the bed of the machine, and towhich the df metal ofthe width of a staple, and ,at its sides of the thickness of a staple. Centrally is thickened, as shown in the drawings, in or- `Ader toenable it to withstand the strain '.o which it is subjected at this point. The plunger is connected to the upper side of the stapassesthrough the piece 3S fastened to the bottom of the staple holder, 7o I thus press the lower arms-of said levers out- 75 I'I. The staple 'inserting mechanism-The 8o plunger is, connected by a 85 link connection. The plunger is a piece and longitudinally of the same is formed the slot or groove 4l, around which the plunger '9o ple guide block by means of a pin 42,which 95 into the head 31, vin such a manner that when the plunger is in its upper posi-tion, as shown in Fig( 5, the -lower end of the said plunger is just above the` passage way through which the staples` roo pass into the staple guide way. The plunger is normally held in this position by the spring 39, which, attachedl to the uppersurface of the staple holder head, presses against the lower side of the end of the rocking arm 45, 105 and maintains a constant distance between v the staple holder and Athe said rocking arm. When, however, the staple plunger is caused to descend, it moves from this position through the extreme range of its movement no into the position shown in Fig. 6, with its lower end iiush with the bottom of the staple guide block 30, forcing Adownward by such 'movel ment the staple which is lin its path, and inserting the sameinto 'the fabric. The slot 4l I 15 is of sufficient length' to allow this movement. The'removable piece`38,as shown in Fig. 11, is'cut away so as to fit the peculiar shape of the plunger, andto aiordA the .same-a secure guide. {Ihe rocking arm 145, to which the :zo plunger 40 is connected by a suitable link connection 44," is of the shape -shown in the drawings, and is pivoted between lugs 47, ris. ing at the extreme base 'of the bed 2 of the machine.V Al portion of it extends downward rz 5 below the surface of the table 1, passing through an aperture `in the machine base, and is operated by the operative mechanism in snclra manner as to cause-the arm torock upon-its axis,.and thel upper portion of the 13o --sarne to move forward` and downward, carrying the staple plunger down to the central aperture in the machine bed. The link cohnection of the plunger with the rocking arm againstthe bed plate 6, the said head may tit perfectly even on the same. 0n its front surface, which is perfectly smooth, and which is fiush with the extreme end of the staple holder, around which -the head is indeed' formed, and ona plane at right angles to the length of4 the staple holder, are cut guide ways for the sliding gates 32, whose outer sur- 'faces are thus iiush with' the surface of the 40 head 31. One of, thse sliding gates is shown in detail in Fig, 14. It is a rectangle of metal, having an oval slotcut in its outer end, and having the inner surface of its re'ar end, as well as of its sides, beveled. It has two positions. In its outer, normal position, it is, vas shown in Fig. 5, drawn outward until the inner end of thesame is clear of the passagel wayA throughwhich the staples pass. In its-closed position, each gate acts ton-close up neside. 5v f this passage way, thuspreventng another staple from being forced ont of-l the holden The beveled edge permits this cutting oifto be performed with great-ease and accuracy. jl TheA sliding gates are actuated by means of the'le'- vers 33, acting through the pins 34, which pass through theoval. slots formed inthe gates as before mentioned. The levers 33-are pivoted` to the upper portion of vthe head 31, and ex'- tend abovesaidhead, so that when the upper 6o ends of the said levers are forced outward, the lower ends are forced inward, thereby closing the sliding gates`32, and shutting off the 'supply of staples. The oval form of the apertures in the sliding gates permits the radial inward movement of the pins 34, while allow- 1 ing the gates to reciprocate back and forth in a straight line. T he gates are normally held 30 inclined so that when the guide block rests Url) front of thejsaid strips. .Vhen, therefore, the

:rocking arm is depressed, and moves forward and downward, the upper ends of the levers ride on the inclined ends of the strips l0 uu- -t'ormed with a lug 50 on one til the level portion ofthe saine is reached, and then duringthe further movement ofthe rocking arm slide along the level portions of the strips without any lfurther outward movement. 'l`he`outward movement of the upper ends of the levers 33 causes an inward movement et the lower paris ofthe same, and thus closes the sliding gates i512. The upper portion of the rocking arm l5 is normally held raised by the spring 5l, which, attached to the rear, 'ierpendicular portion of the inachine bed Lpresses against the same. It' the pivotal sumnort ot' the staple holder 1ne borne in mind, and also the fact that it is held elevated from the machine bed hy lbeing connected with the rocliingarm 45, it will be seen ing the llrst part et' the niovementof said r ching arm, the staple holder is forced downward, the said holder turning upon its apio guide bloeit strikes the pivot until the bed plate When the end et' the movement is reached, the staple plunger descends, and forees the staple into the cloth. lt is during the first part of the movement of the rocking arm, while the staple holder turningon its pivot, that the sliding gates 32 are closed. rl`hus the gates are closed, and the outward passage of the remaining staples prevented before the staple plunger has begun to de` sccnd, and the said sliding gates are not opened until the staple plunger is completely raised. There is therefore no opportun-ity Yfor the staples to getturned or twisted out of their position in the staple guide block, lfn ringthe reeiproention ol' thepiungelgits smooth reart'aee slides against; the smooth inner face ot the staple guide block. 'lhe staples are heid in position` in the staple guide bloelnat ter they have been forced into the saine by the feed piunger, by friction. The rocking arm is formed at its rear with an opening 4S, through whichl the tube 13 passes. The opening is so shaped as to permit the radial movementot said tube during the operation of the machine. The said rockingarm is also side of the same, at a point just above its pivot. lhislug perform-s a function in operating the plate feeding mechanism which will hereinafter he noted. l

lll. Tzeploe holding and fefflz'ng denim* The plate holding and feeding device consists ol a lrolder for the plates, and means for successively forcing each plate into position over ,through an opening in the central aperture. lhe plate holde'; isla tube 55, shaped so as to receive the plates, to the bot-tom of which is connected the tube 60, which contains a coiled spring designed to operate the pressure plunger 57, which acts to force the plates upward. The plates are held, previously to being placed on theirholder, upon a strip ot' paper, or other suitable material, a single charge for the machine,rsay a gross, being threaded upon each strip. Ihe holder is provided with a removable cover 56, which extends the whole length of the same, and the bottom end of which 1s provided with a curved or bent projection, which enters into a slot in the top of the tube 60, and thus partly holds the cover on the tube.

A Ushaped piece 5S, which slides over the cover, completes the locking of the amonio the holder. The plunger 57 is p.o\/1ded at rts lower end with a handle 57', by means of which the plunger can be drawn down to the bottom ol the plate holder 55, and then, by turningl the handle into a slot formed 1n the tube G0, permanently locked in its withdrawn position. When it is desired to charge the plate holder, the plunger 57 is withdrawn, the cover: 5U of the holder removed, and the plates placed in the holder. rlhe cover is new locked in position, and the paper upon which the plates were threaded withdrawn. To place the plate holder in position on the machine, its upper end is inserted through au ope-ning in the t.al le,and pushed upward the machine bed, which is fitted to receive it, until the stop Gi gives Warning' that the extreme upward movement has been reached. 'lhe upper end of the holder sthen flush with the top of the machine bed. A pawl (i2, pivoted to the bottom of the machine bed, is now turned until one of its arms prc-ssesagainstthe holder, and holds it in place by frictional pressure. Lengthwise of theplate (l and ot the width of a reinforcing plate is cut a slot 63, which is Covered, with the exception of its extreme front end, by a'metal plate 6l, whose under surface is thickened direetlyover the slot 63 so as to makethedilterence between the bottom of the plate 6' and that of the plate 6e equal to the thickness of one reinforcingplate. The extreme front portion of this slot, which is rounded, has been given `the designation 7, and its purpose has been stated as holding the plate in position over the een-l tral aperture. 'ihe formation ot' the front ot' this aperture, as shown in Fig. 1, enables the plates to vbe picked ontot the same when desired without difficulty. \Vhen the plate 6 is in position on the bed of the machine, the

slot 65S is over the horizontal portion ofvsaid bed. Upon the top of the bed, and guided by the walls of said slot, reciprocates the plate t'eed plunger (i5, Whose width iS that of the slot, and whose thickness is that lof a reinl'oreing plate, or such as to cause its top surface to fit snugly against the bottom surface ot' the plate Gl. 'lhe plunger is attached at its rear end to the metal piece 66, which extendsv across the machine bed, and is situated ina recess or depression in the same, so that its upper surface is level with the machine bed. This piece is'connected at one side by means cf the rod 67 to the upper endof the lever 68, which is pivoted tcQthe side of the machnie bed; Thelower, curvedend of this lever rests against the lug'50 formed on the rockingarm 45 in such amanner that when the said' rocking arm is depressed, the lever 68 will be caused to turn on its pivot, and'draw back the metal piece 66, and thereby the plunger 65. The recess formed in theV machine bed vin which the said piece 66 rests permits of such backward movement. When the plunger isin its normal position, it is forward with its frontend nearlyou a line with the central aperture, but 'when the plunger iswithdrawn through the depression of the rocking arm, and'parts acting in connection therewith, its front end is drawn back to a position just behind the cud of the plate holder. If 'n ow .he plunger 57 be allowed to press vagainst the plates, it will force the top .plate against t-lie surface of the reciprocating feed plunger 65. When this is withdrawn, either 'through the action of the rocking arm, or by drawing back'the connecting rod 67 by hand,

the top plate will be forced up against thelower surface of the plate 64. Only one reinforcingplate can be thus forced up,how ever, because of thethickness of the plate 64. When the feed plunger now moves forward, it will carry with it this plate, andwill force it into position over the central aperture, in position to have the proper actionv take place thereon. Bearing in iniudthe operation of the rocking arm, it willv be observed that when the same is being depressed, and thus causing the operation of the staple inserting mechanism, the plunger 65 is withdrawn, and a new platefoi-ced into position .to be carried forward by said plunger, and thus to replace the plate just used. When the rocking arm rises,-the said plate is forced into its operative position. The feeding forward of the plate thus takes place at the same time that the feeding of the staple takes place. The formation and arrangement of the parts herein descrbediire such as to prevent two plates being fed forward at the saine time, or any confusion of the feeding of the staples to arise.

IV. The clinchiigmechanism.;'1`he clinching mechanism consists of two curved blades,

. situated in the lcentral aperture, which normally hang with their upper ends apart, but

which are so operated by the hammer actu? ating the saine that the upper ends are brought together, thus bending the legs of a staple together, and then the entireblades Aare given an upward movement, which performs. the final clinching. vThe front. end of the maehine bed 2 is chiseled away to permit the insertion of the metal pieces 7l, which project downward below` the machine bed The outer face of the same is level with the front of the machine bed -On these project- I ing pieces 7l `treformed the supporting pins 69, on which are hung the curved blades 70.

`rFhese curved blades perform the clinching of the staple. One'of themis shown in detail t in Fig. l2. As there shove the blade consists of an upper portion 73, substantially rectangular in form, from which depend .the curved wings 73. In the blade is formed an oblong slot 74, through which the supporting pin (i9 passes. The blade is. thickened around this slot, as it is here subjected to the greatest strain, the plate 5, which holds these blades in position, being cut away accordingly. .On

vthe upper edge of the blade, and on `the inner The surfaces 76 and 77 upward, the oblong slot through which vthe .supporting arms pass permitting such move-v ment, and the upper surfacesv of the blades which are now on a line with, and just alittle below the surface of the machine -bed 2, to-

gether with the lugs75, act to positively and eifectually clinch the legs of the staple into the cloth, and around the reinforcing plate. The purpose of incliiiing the surfaces 76 and 77 is nfow apparent; It is so that the said surfaces-may be level with the machine bed at the proper instant of time. These blades are operated by means of aliammer 80, which is pivoted to a lug projecting from the bot- .;tom, rear surface of the-machine bed 2. This hammer is in effect a bell crank'lever, whose short arm extends under the table, and is 0perated 'upon by the operative mechanism, and. whose long ar'm extends forward to operate` the clinch'iug blades. We designate this long arm, however, as. the hammer, as it in reality performs the hammering requisite to clinch the staples. In an aperture in the hammer 80, through the rear portion of which the plate holder 55 passe's,and through which the cuived wings 7 3 pass, is-foruied the V-shaped.

lug 8l, which occupies the spacebetween the curved wings mentioned. The operation of ,the hammer is clearly apparent from Figs. 8,

9, and lO. When the hammer is raised, the V-shaped lug 8l forces apart the lower ends ofthe curved blades, causing the lugs 75 to approachvea-cn other, and thus bend inward the legs of the staples.

When the'upper sur'y I OQ face of the hammer reaches the surface 77 of the blades, it forces the entire blades upward, and thus causes the final clinching. When the hammer is lowered, inc i'feigdit of the same causes the blades to separate, and the curved wings to draw together, as the Whole Weight of the hammer is sustained by the said wings.

V. The operative mcchansm.-The operative mechanism for the machine is a bell crank lever 90, which is hung upon a shaft 91, journaled on the lower Yside of the table in suitable supports, and which is actuated by a crankarm 93, which in turn is operated by the arm 94, pivotally attached to it, and which is connected at its lower end to an ordinary foot treadle. A spring 96 normally holds the bell crank lever 90 in the position shown in Fig. 2. By the depression of the treadle, the lever is caused to rotate, one arm 90 of the same striking the lower curved portion of the rocking arm 45. This portion of the rocking arm is curved so as to make the movement of the upper part gf the saine more uniform. The rocking arm is thus depressed until it has reached the lowest phase of its movement. By this time the portion 90 of the lever 90 has completed its possible movement upon said rocking arm. The arm 902 of the lever 90 now strikes the lower projecting portion of the hammer 80, and causes the same to turn upon its pivot, and perform the clinching operation. The hammer does not act to clinch the staple, however, until the staple has been driven home in the goods.

Operation: After the staple holder, and the plate holder have been nut in position, and the pressure plungers operating upon the same have been brought into action, the machine should be placed in operative position by drawing back the plate feed plunger 65, and placing a plate in position over the central aperture. The goods to be operated on should then be placed in position under the staple inserting mechanism. Upon the depression of the operative treadle, the bell crank lever 90 is turned, and the arm 90 caused to strike the lower portion of the rocking arm 45. This causes the upper portion ofthe saine to be turned on its pivot, and after the staple holder has been moved so that the staple guide block is over the central aperture, with the staple guide in registering connection therewith, during which movement the sliding gates have been closed, and the feeding of another staple prevented, the staple plunger is caused to descend, and the staple is forced into the goods. During this operation the reciprocating plunger 65 has been drawn back, and a plate has been forced into position to be carried forward by the next forward movement of the said plunger. The apparatus is now in the position shown in Fig. 3. Upon further descent of the treadle, the arm 902 of the lever 90 strikes the lower arm of the hammer 80, causing the upper portion of the same to rise, and thus Separate the wings of the clinching blades, thereby forcing together the legs of the inserted staple, and then causing the clinching blades to be forced upward, and the legs of the staple to be securely clinched. The machine is now in the position shown in Fig. 4. Then the treadle is raised, the hammer rst falls, forcing the clinching blades apart, and placing them in their normal position; and then, on further elevation of said treadle, and consequent movement of the bell crank lever, the rocking arm rises, a plate is forced into position over the central aperture, and, the sliding gates in the staple holder at this point opening, another staple is forced into position to be operated upon. The machine is now 1n condition to repeat its former operation.

Having thus fully described our machine, its construction and operation, what We claim as new, and desire to secure by Letters Patent, is
